Aesop's Fables, translated by Laura Gibbs (2002)

Do no harm - if someone does get hurt, then turn-about is fair play,
as this fable cautions.
The fox is said to have started it by inviting the stork to dinner and
serving a liquid broth on a marble slab which the hungry stork could not
so much as taste. The stork, in turn, invited the fox to dinner and served
a narrow-mouthed jug filled with crumbled food. The stork was able to
thrust her beak inside and eat as much as she wanted, while her guest
was tormented with hunger. As the fox was licking the neck of the jug
in vain, the stork is supposed to have said, 'When others follow your
example, you have to grin and bear it.'

Note: Caxton (2.13) supplies the English
proverb 'with the staf which he had made he was bete.' The story of
the fox and the stork is also found in Plutarch, Symposiastic Questions
1.1.
